Hyperspace as a game/story mechanic

sobriqueOne of the problems with science fiction, is that space is big.
Really really big.
There's lots of different ways of handling it. Most do so by some form of faster than light travel.
Too many overlook it though, since it makes a big difference to the 'feel' of your setting - how easy it is to travel.
Sometimes you have "FTL isn't possible" scenario. Where everyone obeys relativistic physics. There aren't many examples of this, although perhaps the most famous would be Arthur C. Clarke, and his 2001, 2010, 2061. In these, the journey is a major part of the story - travel around the solar system takes months. Often there's the concept of 'continuous acceleration' ships - the physics being cheap fusion power, throwing particles out of the ships sufficient to sustain 1G of acceleration all the way. (The ship turns around mid flight and decelerates the final stages)
It works well enough, but (off the top of my head) this makes Jupiter weeks away, and our Solar system the limit.
Another common mechanic is 'warp' drive. Faster than Light travel through real space. Most obvious example being 'Star Trek' where they distort space time, such that they're travelling through real space, but 'cheating' to avoid the light speed barrier.
It makes for a 'simpler' conception of the galaxy - they 'almost' ignore the light speed problem, and all they need is a special engine to travel quick. (Although they do have relativistic issues when travelling with 'impulse' engines).
The third method that's often seen is 'hyperspace'. A realm of space, connected to 'real' space, but usually smaller. Or of a different topography, such that moving the 4 light years from Sol to Proxima centauri doesn't involve covering the same distance.
Motion through hyperspace typically _also_ takes a different kind of propulsion - sometimes just to 'jump' sometimes to sustain.
In star wars, hyperspace is not a 'natural' place for a ship to exist - if the hyperdrive cuts out, ships leave hyperspace (although sometimes that means they're proper fecked). The 'speed' through hyperspace depends on the 'power' of your hyperdrive. A hyperdrive in star wars is also sufficiently small to be on fighters - all the rebel starfighters - A-Wings, B-Wings, X-Wings and Y-Wings can travel through hyperspace. Although being in small cockpit for extended periods of time isn't stunningly comfortable.
Babylon 5 universe is similar, but with one important difference. Hyperspace _is_ stable in B5, so a ship can enter hyperspace and stay there.
In B5 this was originally accomplished via the Jump Gates in each Solar system, but there was an evolution of 'ship based' hyperdrives. Most of these only on the very large capital ships (one of the reasons that large ships are necessary).
It does make for a different plot device - getting 'lost' in hyperspace is a very real possibility (where in star wars, getting 'lost' was still possible, but it'd be in real space as you ended up in the middle of no where between stars).
The fourth possibility is 'star gates'. Mystical thingies that people can use to travel between two fixed points. Or maybe they're just 'warp points'. They're finite and fixed. If you want to go to $location, you have to start from $other location.
And finally you have the 'mystic navigator' system. Dune and the Warhammer 40k use them. Special individuals who can in some way move things the size of space ships across the intervening void. This is actually one of the cooler ones - it's a 'human aspect' to your space travel, rather than just a technological solution.
The universe and stellar distances are approximately fixed. The _real_ distance is how long it takes to get there. Occasionally you see others show up, such as the 'mathematics' travel that David Zindel uses in Neverness. Sort of a variant on the mystic navigator, it's also more detailed, and ... well worth a read just for the explaination of hyperspace travel.
So now I have a question. Which do you 'prefer' for your GMing, story telling, or in films/TV?
And is there any (examples or methods) that I've missed in this selection of plot devices?

This is currently a bit of preoccupation for me - trying to find a fictive FTL device that doesn't permit hundreds of time travel paradoxes.
time travel paradoxes.

Date: 2004-09-30 05:48 am (UTC)I don't see it as much of as suspension of disbelief to allow that to be taken notably further.
I thought though, that there just isn't "faster than light". You can take 'shortcuts' but can't move faster than this absolute limit.
A static wormhole does imply time differences, with differing velocities of the entry and exit point, but I've always taken the view that it doesn't really matter overly if proxima centauri is 4 years 'in the past' or 'in the future' as long as theres at least some coherency in the temporal mechanics.
I daresay that we may have physicists prove these things one way or another at some point, but I don't think they'll ever lose their value as storytelling devices.

Date: 2004-09-30 06:58 am (UTC)In relativity, two different observers can disagree about which of two events occurs first. This normally isn't a problem because neither event exists in the other's light cone. They occur close enough together in time and far enough apart in space that a signal from one will not be able to reach the other.
Once you start allowing information to move faster than light, however, even by the use of wormholes or what-have-you. You violate this assumption which makes for very tangled causal relations between events.
